可再生能源是防止危险气候变化的基石，同时保持强劲的能源供应。潮汐能可以说将在可再生能源组合中发挥关键作用，因为它既可预测又可靠，并且可以在地球仪各地部署。然而，安装可能会通过潮汐动力学、沉积物迁移路径或水深变化的变化影响当地和区域生态。为了减轻这些影响，需要对潮汐能装置进行建模，以预测水动力变化。稳健的网格生成是开发高精度仿真所需的基本组件。然而，网格生成沿海地区可以是一个复杂的过程。在这里，我们描述了一种方法相结合的网格生成器与地理信息系统。我们证明了鲁棒性和效率，通过构建一个网格，以检查潜在的环境影响的潮汐涡轮机农场安装在奥克尼群岛。网格，然后使用两个经过验证的海洋模型，比较他们的流量预测与没有涡轮机阵列。结果表明，可以创建一个易于使用的工具来生成高质量的网格，用于组合沿海工程，这里是潮汐涡轮机和沿海海洋模拟。
Renewable energy is the cornerstone of preventing dangerous climate change whilst maintaining a robust energy supply. Tidal energy will arguably play a critical role in the renewable energy portfolio as it is both predictable and reliable, and can be put in place across the globe. However, installation may impact the local and regional ecology via changes in tidal dynamics, sediment transport pathways or bathymetric changes. In order to mitigate these effects, tidal energy devices need to be modelled, to predict hydrodynamic changes. Robust mesh generation is a fundamental component required for developing simulations with high accuracy. However, mesh generation for coastal domains can be an elaborate procedure. Here, we describe an approach combining mesh generators with Geographical Information Systems. We demonstrate robustness and efficiency by constructing a mesh with which to examine the potential environmental impact of a tidal turbine farm installation in the Orkney Islands. The mesh is then used with two well-validated ocean models, to compare their flow predictions with and without a turbine array. The results demonstrate that it is possible to create an easy-to-use tool to generate high-quality meshes for combined coastal engineering, here tidal turbines, and coastal ocean simulations.
